Tool set with 5 T-handle screwdrivers for hexagonal socket screws. With extra-long blades for low-lying couplings. Hex-Plus offers larger contact surfaces in the screw head. The notch effect is reduced to a minimum and the destruction of the screw is nearly eliminated. With holding function to hold the hexagonal socket screw securely on the tool. Particularly suitable for operations in plumbing, heating and air conditioning. T-handle screwdrivers: The ideal handle shape allows the transmission of particularly high tightening and loosening moments. The ergonomic shape of the handle fills the ball of the hand well, the fingers lie securely in the softly rounded recessed grips. The whole hand comes into contact with the handle and friction losses between hand and handle are avoided. Special surface treatment of the blades for high corrosion protection and optimum fitting accuracy in the screw.
